General

General
The overhead guard is an integral part of operator
cab. The operator cab is installed on a platform above
main frame members. Step plates on both sides of lift
truck provide access to operator cab. The operator

cab is a separate unit and can be removed as a
complete unit from module and frame of the lift truck.
See Figure 1.

WARNING
DO NOT remove the radiator cap from the radiator
when the engine is hot. When the radiator is hot
and the cap is removed, the pressure is released
from the system and the steam and boiling coolant can cause burns. Wait 30 minutes for the engine to cool. Do a touch test by touching the radiator with your hand. If the radiator is still hot to
the touch, wait another 30 minutes before attempting to remove, check, or fix any part of the
cooling system.
NOTE: Removing radiator cap will help depressurize
cooling system.
4. Remove radiator cover to access radiator cap.
Remove radiator cap. See Figure 5.

CAUTION
DO NOT allow any fluid to drain when disconnecting the heater hose from the engine. The method
will help when purging the system during installation.
5. Disconnect and cap heater hoses from engine.
See Figure 6.

WARNING
Replacement, installation and repairs to air conditioning units that require discharging and/or refilling of the refrigeration fluid must be performed by
a certified technician.
6. Contact a certified air conditioning specialist to
have the refrigerant extracted from the air conditioning system.
NOTE:
Step 7 is for lift truck models GLP/
GDP40VX5/VX6;
GLP/GDP45SVX5,
GLP/
GDP45VX6; GLP/GDP50-55VX (GP/GLP/GDP080,
090, 100, 110, 120VX) (G813, H813, J813) with a
Cummins QSB 3.3L or a Kubota diesel engine.
7. If lift truck cab is equipped with an air conditioner/
heater unit, disconnect AC refrigerant hoses from
refrigerant compressor.

WARNING
Make sure that the lifting device has a minimum
capacity to lift 500 kg (1100 lb).
28. Connect a lifting device to a spreader bar or lift
strap, that is through door openings at top of operator's cab (under overhead guard structure).
Place material that will be a cushion at top of door
opening to prevent damage. Operate lifting device
just enough to correctly position spreader bar or
lifting strap on operator's cab. See Figure 21.

CAUTION
Lift the operator cab carefully. Check that all electrical wires and attachments are disconnected
and are not damaged.
29. Carefully lift operator cab away from lift truck. Set
operator cab in a storage area and place blocks
under operator cab to make it stable and prevent
damage to parts still attached.

WARNING
Replacement, installation and repairs to air conditioning units that require discharging and/or refilling of the refrigeration fluid must be performed by
a certified technician.
32. Contact a certified air conditioning specialist to
have the refrigerant refilled into air conditioning
system.
33. On lift trucks equipped with an air conditioner/
heater unit, start engine and turn on heater to ON
position, run engine approximately 1 to 2 minutes
or until heater supply hose is fully purged.
NOTE: The EZ Tank Bracket used on these trucks to
mount LPG tank onto counterweight comes in two
styles. One style of bracket swings out to side of truck
and other swings out to side and drops down.
34. Lift trucks equipped with a LPG engine, swing EZ
Tank Bracket back to its original and locked position.

WARNING
Make sure that the lifting device has a minimum
capacity to lift 500 kg (1100 lb).
26. Connect a lifting device to a spreader bar or lift
strap, that is through door openings at top of operator's cab (under overhead guard structure).
Place material that will be a cushion at top of door
opening to prevent damage. Operate lifting device
just enough to correctly position spreader bar or
lifting strap on operator's cab. See Figure 31.

CAUTION
Lift the operator cab carefully. Check that all electrical wires and attachments are disconnected
correctly and are not damaged.
27. Carefully lift operator cab up and away from lift
truck. Set operator cab in a storage area and
place blocks under operator cab to make it stable
and prevent damage to wire harness and parts
still attached.

17. Install front wiper motor cover using three lock
nuts. See Figure 27.
18. Install right side front cover to front overhead
guard leg using two screws. See Figure 25.
19. Install right side rear cover to right side front cover
